Sometimes referred to as “Big Blue” IBM is a multinational corporation headquartered in Armonk, New York. It manufactures computer hardware and software and provides information technology and services.
(1) Data that is recognized only by the procedure or OPM program that defines it. Local data is deleted when the procedure returns control to the calling program or procedure. See also external data.<br />(2) In COBOL, the data described in a program excluding all external data items and external file connectors. Items described in the Linkage Section of a program are handled as internal data.
Industry:Software
(1) In REXX, the parts of a parsing template that allow a string to be split by literal pattern or positional pattern. Parentheses may be supplied to create a variable pattern.<br />(2) A sequence of characters used either with regular expression notation or for path name expansion, as a means of selecting various characters strings or path names, respectively. The syntaxes of the two patterns are similar, but not identical.<br />(3) A reusable description of the design and architecture, which is used to satisfy defined criteria.
Industry:Software
(1) In RPG, a literal or field name specified in factor 1 of certain file operations (such as CHAIN) that identifies the record to be processed.<br />(2) The conditions specified when searching, consisting of one or several search terms and search parameters.
Industry:Software
(1) A string of characters that uniquely identifies a user to a system. See also user identification.<br />(2) The name by which a user is seen by other users. This name is entered, along with a password, when the user logs onto the Sametime server.
Industry:Software
(1) For interactive jobs, the system to which the display device is directly attached. For batch jobs, the system on which the job is being processed.<br />(2) In an IMS multisystem environment, a specific system in the multiple configuration.<br />(3) In a multisystem environment, the system on which an application program is executing. A local application can process data from databases located on either the same (local) system or another (remote) system. See also remote system.
Industry:Software
(1) A structure that contains an ordered collection of data elements in which each element can be referenced by its ordinal position in the collection. All elements in an array have the same data type.<br />(2) An arrangement of data in one or more dimensions, such as a list, table, or multidimensional arrangement of items.<br />(3) An arrangement of related hard-disk-drive modules that have been assigned to a group.<br />(4) In programming languages, an aggregate that consists of data objects, with identical attributes, each of which can be uniquely referenced by subscripting. See also vector, scalar.<br />(5) In EGL, a structure item that has an occurs value greater than one. If an array has a subordinate structure item that also has an occurs value greater than one, the subordinate structure item declares an array with an additional dimension.<br />(6) A number of items stored together, which a user can quickly retrieve by supplying the correct index.<br />(7) An ordered collection, or group, of physical devices (disk drive modules) that are used to define logical volumes (LVOLs) or devices. In the ESS, an array is a group of disks designated by the user to be managed with a Redundant Array of Independent Disks (RAID). See also Redundant Array of Independent Disks.
Industry:Software
(1) For processor storage, real and virtual storage, and channel volume, 2 to the power of 10 or 1024 bits.<br />(2) For disk storage capacity and communications volume, 1000 bits.
Industry:Software
(1) For the IMS subsystem, the first 1 to 8 characters of the first segment of a message sent to IMS/VS. The transaction code identifies the application program for which the message is intended.<br />(2) A 1- to 8-character alphameric code that invokes an IMS message processing program.<br />(3) In IMS and CICS, an alphanumeric code that calls an IMS message processing program or a CICS transaction. Transaction codes have 4 characters in CICS and up to 8 characters in IMS.
Industry:Software
(1) A subset of a data entry database (DEDB) that is defined as a VSAM entry-sequenced data set (ESDS). Each area in a DEDB consists of a root-addressable part, an independent-overflow part, and a sequential-dependent part. Areas contain the entire logical structure for a set of root segments and their dependent segments.<br />(2) In a link-state routing protocol, groups of contiguous networks and attached hosts. An autonomous system can be divided into areas, which are connected to each other by routers. Routers within the same area share an identical link-state database. See also autonomous system.
